Blindspot vs Vistar: storefront vs plumbing

The verdict: who each is for

Vistar Media and Blindspot sit at different layers of the same category. Vistar is enterprise programmatic infrastructure for out-of-home: a supply-side platform, a demand-side platform and an ad server, reached through a DSP seat or an enterprise contract, buying audiences across one of the largest aggregated supply pools in the category. Blindspot is the marketplace end: 3M+ digital screens in 50+ countries, a named screen booked for a named hour, priced per play from $0.23, with contextual triggers and measured attribution.

A fair comparison starts by telling the two buyers apart, because these two rarely compete for the same brief. An agency or in-house team that already buys every channel through a demand-side platform, and needs out-of-home to appear as one more line in that stack with the same segments and reporting, is Vistar's buyer, and its rails are built for exactly that. A brand, founder or growth team that wants to open a map, read a per-play price on a named screen, book only the commuter hours, trigger creative on live conditions and measure the outcome is Blindspot's buyer. One honest note before the detail: Vistar is infrastructure a great deal of the category runs on, including supply that reaches buyers through other platforms, so calling it a rival oversimplifies. Where the two do overlap, on getting a digital screen to play your creative, this guide compares them plainly.

Vistar vs Blindspot, line by line

The dimensions that actually decide the choice. Blindspot figures are from live platform data, Q3 2026. Vistar Media is described from its own published positioning and the industry coverage cited below; where a comparison is not like-for-like, the row says so.

Blindspot figures are from live platform data, Q3 2026. Vistar Media's model, access route and supply position are described from its own positioning and industry coverage, 2026; it does not publish a fixed per-play rate, so its pricing row describes the programmatic buying unit rather than a quoted figure. The two are different by design, so the next section works a like-for-like example. See also our wider platform comparison.

Pricing: the unit, worked

The unit is where these two genuinely diverge. Vistar sits in the programmatic world, so the buy settles as a CPM against a modelled audience, priced at auction or negotiated inside a deal, and the number you paid becomes clear after delivery. Blindspot prices the screen itself: one play, one appearance on one named screen, from about $0.23 on urban screens, shown on the screen card before you commit.

The difference is not cosmetic. A CPM is a forecast of an audience; a play is a fact you can audit, logged with a time and a place. On CPM you pay for a modelled number of eyes; per play you pay for appearances that actually ran.

A worked example. Say the brief is one commuter corridor in a single city for two weeks. Through Vistar the corridor is expressed as an audience segment and a geography, the DSP optimises delivery across whatever supply clears, and the report tells you what it cost per thousand afterwards. On Blindspot you select the screens on that corridor by name, set 7am to 10am and 5pm to 8pm on each of them, and read the per-play price before you commit: at about $0.23 a play, a $500 budget buys on the order of 2,000 plays placed only in those windows. Both routes can cover the corridor. One optimises toward an audience; the other lets you name the screen and the hour and see the price first.

Neither unit is wrong, they answer different questions. If the plan is stated as reach and frequency against an audience across many channels, a programmatic CPM is the native language. If the plan is stated as places and times, per-play buying is. For the full pricing picture across formats and cities, see the billboard cost guide.

Attribution: what you can measure

Vistar is an enterprise stack, so measurement arrives the way it does elsewhere in programmatic: impression-level delivery, audience verification and the attribution products an agency already runs across channels. For a team that reports out-of-home inside one omnichannel dashboard, that consistency is the point.

Blindspot starts from a receipt rather than a model: verified plays logged with a screen, a time and a place, then measured lift on top. Outcomes have been measured against a control group at around $0.82 per incremental store visit, $0.80 per incremental web visit and $5.75 per incremental online purchase. Set that against paid-social costs per action that often run from $15 to $40, and a well-scheduled digital out-of-home campaign can compete on cost per outcome, not just on reach.

That loop is also what makes hourly buying pay off. Because Blindspot knows which plays ran and can tie delivery to foot-traffic and web lift, it can concentrate a budget into the windows that convert. A worldwide tourism campaign did exactly that, delivering 87% more plays than planned on the same budget. If measured outcomes matter to your plan, that is a real reason to choose Blindspot; if a delivery report against an audience is enough, it is not.

When to choose Vistar

There are real briefs where Vistar is the right rails and Blindspot is not. Choose Vistar when:

Out-of-home has to sit inside your DSP. If your team buys every channel through a trading desk and out-of-home must appear as another line in the same stack, with the same deal IDs, audience segments and reporting, that is exactly what Vistar's rails are for. Blindspot is a marketplace, not a DSP integration, so it will not slot into that workflow the same way.

You are buying an audience, not a place. When the brief is a segment and a region rather than named screens, audience-first optimisation across a large aggregated pool is the more natural fit. Vistar is built to spread delivery across supply toward that segment; Blindspot is built to let you pick the screen.

You are a media owner looking for demand. Vistar's supply side exists to connect operators to programmatic demand. If you run screens and want them sold through the DSPs agencies already use, that is its job, and it is not something a buy-side marketplace does for you.

If your brief looks like any of those, Vistar is a genuinely good answer, and agencies often run both: the DSP rails for omnichannel programmatic, and a marketplace when a client wants named screens, named hours and a line-item price.

When to choose Blindspot

Blindspot is the better tool when the brief names places and times, and when price visibility, hourly control or measured outcomes matter more than fitting inside a DSP. Choose Blindspot when:

You want hour-by-hour control per screen. Blindspot sets a schedule for each screen down to the hour, so you can run only the commuter peaks, an evening window, a weekend or a single event, and skip the empty overnight hours a broad buy still pays for. Cutting those dead hours typically removes 30% or more of the waste and puts the same budget into the windows that carry your audience.

You want the price before you commit. Every screen shows its per-play price before you book, from about $0.23, with no minimum spend, retainer or platform fee. A real campaign can start for a few hundred dollars, and the same platform scales to a global flight when the budget grows.

You need reach beyond one market. With 3M+ digital screens across 50+ countries, and 25,000+ advertisers already on it, Blindspot books New York, London, Dubai, Seoul and Bucharest from the same map, one account, one invoice.

You want contextual creative and measured outcomes. Blindspot triggers creative natively on live conditions: weather, temperature, air quality, stocks and crypto, live sports scores and any custom live-data API. Delivery is logged as verified plays, and measured lift has come in around $0.82 per store visit, $0.80 per web visit and $5.75 per online purchase against a control group.

You can open the map, read real prices on a self-serve platform, set an hourly schedule per screen, and have Blinky build a plan from a one-line brief.
